Raising the efficiency of polycrystalline cells with new luminescent EVA film
Chinese researchers have developed a pure EVA film, which they claim can enhance the conversion efficiency of conventional crystalline solar cells by around 0.50%. The film is able to convert UV light into strong visible light.
A new technique to get the right angular-tilt for PV panels
A U.S. scientist is proposing a new approach to calculating the optimum angular-tilt of PV panels for a planar surface at a particular site. In his view, the new technique may unlock innovative yield-optimization methods for the installation of PV systems.
Israel launches 300 MW solar-plus-storage tender
The Israeli government wants a 300-megawatt solar plant linked to large-scale storage in the Negev desert. Construction is planned for late 2021 and completion in 2023.
Qatar’s 800 MW tender draws world record solar power price of $0.01567/kWh
The winning consortium was formed by French oil giant Total and Japanese conglomerate Marubeni Corp.
All-inorganic perovskite solar cell hits 16.1% efficiency
Researchers from the City University of Hong Kong have developed an all-inorganic perovskite cell with an electron-pair donor which offers a pair of non-bonding electrons. The cell was developed by applying that ‘Lewis base’ small molecule to passivate the inorganic perovskite film.
Panasonic claims 16% efficiency for lightweight perovskite solar module
The device has an area of 802cm² and thickness of 2mm. The manufacturer claims it improved module performance through an inkjet coating method and a reduction in weight by using thin glass substrates.
China will extend duties on US and South Korean polysilicon for another five years
The Chinese government will extend duties on U.S. and South Korean polysilicon for another five years despite committing to buy $200 billion more U.S. goods and services over the next two years in return for America halving 15% tariffs applied to $120 billion worth of Chinese products.
World record efficiency for Longi’s PERC mono, Jinko’s p-type PERC and bifacial solar panels
Solar module efficiency records continue to fall. Longi claims a 22.38% efficiency world record for a PERC mono panel, while Jinko has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively.
Solar modules from Sharp with half-cut technology exceed 19.5% efficiency
The Japanese electronics giant has unveiled three monocrystalline half-cut cell modules said to provide 2% to 3% better performance than standard, full-cell panels. The claimed efficiency of the modules exceeds 19.5% and Sharp says power output ranges from 330 W to 395 W.
US scientists claim clear-sky irradiance model provides better results for module testing
Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.
